Application filed October 8, 1904. Serial No. 227,624.

To all whom ti may-concern:

Be it known that DELAWARE J. H001), a citizen of the United States, and a resident of invented certain new and useful Im rovements, in Talkin -Machines, of which t e following isa ful clear, and complete disclosure, reference being had to theaccompanying drawings, forming a part of this specification.

The main objects of my invention are to provide an im 'roved mounting for a stylus ar; to provi e improved means for connecting a sound box to its'mounting; and to provide other improvements, which will appear in the following specification.

In the accompanying drawings: Figure 1 box and sound conveying arm constructed in accordance with this invention, showing the same in its operative relation tora record tablet; Fig, 2 a similarview'partially in section; 'Fig, 3 a fra mentary top lan view of the ly in'section; ig'. 4 a top plan view of the same but showing the sound box rotated into position for chan ing needles; Fig. 5 a transverse section of the stylus bar mounting taken in the plane of the axis of oscillation of the bar.

R ferring to the drawings,'thedevice eomprises-a sound box 1, of the ty e'used in con nection with sound records aving lateral swinging arm or tube 2 which is pivoted at its larger or inner end 2' in a well known manner to swing in a lane arallel to the disk record 3, of the latera y undulating upon the usual cabinet 3.

For rotatably connecting the sound box with the swinging arm 2, the .end of the arm 2 is rovided with a short transverse sleeve or tu e 4 communicating therewith, which is adapted to telescope over the outer end of a tube or bushing 4"which forms a reduced extension of the rear side'of the sound box casing. The tube 4 is provided with an opening in one side thereof which registers with the openi into the end of the arm 2 when the sound box is in its operative position.

A cap '6 is fitted into the outer end of the l tube 4" and rojects radially beyond the l 4, and a flange 8, upon the innertube 4 contacts against the inner end of the tube 4, and

the inner tube 4 is thus held rotatably in position in the outer tube 4. By this means the sound box is mounted to swing in a plane parallel to the face of the record 3 and to rotate on an axis coincident with the longitudinal axis of the tube 4, substantiall parallel to the face of the record 3 and su stan tially perpendicular to the longitudinal axis of the swinging arm 2.

The mounting for the stylus bar comprises a tube 9 projecting radially and rigidly from the sound box casing and communicating therewith, and the stylus bar 10 extends within and axially of the tube 9. The stylus bar is elongated to correspond to the length of the containing tube 9. The inner end of the stylus bar is phonetically connected to the-diaphragm 11 as usual and the outer end of the bar is mounted to oscillateupon-a torsional spring 12 which extends diametrically of the outer end of the tube 9, the spring; be-

in fixed rigidly both to the bar and to the I tu e. The stylusv bar has the usual SOLkGi and set screw 13 for holding the stylus needle 15 inposition. r

' 1n the present embodiment of this invention, the sound box is restrainedto swing in a-plane parallel to the face of the record, it

is necessary tohave some means for holding the stylus needle yieldingly in contact with the record groove with suiiicient pressure to produce the best results.

For this purpose the walls of the tube 9 are made of sufficient weight to give by gravity thedesired turning movement to the sound box when the sound box is in operative position as shown in Figs. 1 and 2.

It is apparent that the radial tube 9 on the sound box serves not only as a weight to hold the st lus needle in contact with the record,

but a 0 serves as a'protector for the stylus.

bar, and also enables an elongated bar to be used having its axis of oscillation spaced at a greater distance than usual from the inner end of the bar, thus increasing the amplitude of vibration of the diaphra In in reproducing.

When it is desired to'cliange need es the sound box is rotated into the position shown in Fig. 4, and, obviously, stops 16 may be mployed for limiting this movement of the sides of the tu e forming a flan e7 contact- 1 sound box so that the stylus bar may-be remg against the outer ends of bot tubes4 and I tained in a raised inverted positionto facilitate the operation of changing needles and also to keep the stylus needle away from the record when the machine is not in use.

It is evident that in the connection provided by this invention between the sound box and the swinging sound conveying arm there would be butlittlc friction between the moving parts, that the passages are short and conveniently shaped, and that it would not be necessary to lift any of the Weight of the body of the sound box in changing needles or in removing the needle from the record.

Although I have described only one form in which this invention may be embodied, it

IS obvious that many changes might be made in the construction herein set 'forth,-within the scope of the appended claims, to adapt the invention to different requirements and different types of talking machines, Without departing from the spirit of this invention or sacrificing any of the advantages thereof.

Having thus described the nature 'of my invention, I'do not wish to be understood as being limited to the exact arrangement of parts and form herein shown, for the same may be varied to suit different requirements and different ty es of talking machines, but What I claim an desire to orotectby Letters Patent of the United States, is,
